Suppose two different methods are available for eye surgery. The probability that the eye has not recovered in a month is 0.002

antoniya [11.8K]

Answer:

d) 0.4

Step-by-step explanation:

P(Ra) = 0.998

P(Rb) = 0.995

P(A) = 0.4

P(B) = 0.6

The probability that method A was performed, given that the eye was recovered within a month of the surgery, is determined by the probability that the eye recovered within a month with method A (P(A) x P(Ra)),divided by the probability that the eye recovered within a month with either method (P(A) x P(Ra) + P(B) x P(Rb)):

$P(A|R)=\frac{P(A) *P(R_A)}{P(A) *P(R_A)+P(B) *P(R_B)}\\P(A|R) = \frac{0.4*0.998}{0.4*0.998+0.6*0.995} \\P(A|R) = 0.40$
